How much energy in joules, does it take to heat a 55 gram sample of ice from-10°C to

Lostsunrise [7]

Energy needed : Q = 1105.5 J

<h3>Further explanation</h3>

Given

mass = 55 g

Temperature from -10°C to 0°C

Required

Energy

Solution

Heat can be calculated using the formula:

Q = mc∆T

Q = heat, J

m = mass, g

c = specific heat, joules / g ° C

∆T = temperature difference, ° C / K

Input the value :

Q = 55 g x 2.01 J/g ° C x (0-(-10))

Q = 1105.5 J

How many grams of 48.0 wt% NaOH (FM 40.00) should be diluted to 1.00 L to make 0.11 M NaOH? (Enter your answer using two digits.

kifflom [539]

Answer:

The answer is 916.67 g

Explanation:

48.0 wt% NaOH means that there are 48 g of NaOH in 100 g of solution. With this information and the molecular weight of NaOH (40 g/mol), we can calculate the number of mol there are in 100 g of this solution:

$\frac{48 g NaOH}{100 g solution}$ x $\frac{1 mol NaOH}{40 g}$ = 0.012 mol NaOH/100 g solution
